CROSS REFERENCE

This application is a continuation application of U.S. application Ser. No. 17/314,868, filed on May 7, 2021, which is a continuation of application of U.S. application Ser. No. 16/931,157, filed Jul. 16, 2020. The disclosures of the prior applications are incorporated by reference.

TECHNICAL FIELD

The disclosure relates to the technical field of disinfection application, particularly, to a device capable of disinfecting a ventilator as well as a face mask and a hose, and more particularly, to an ozone disinfection device, an ozone disinfection system, and an ozone disinfection method.

BACKGROUND

At present, ozone disinfection methods are commonly used in the fields of medical equipment, catering tableware, food processing, etc. Ozone disinfection is highly efficient and economical. In ozone disinfection of items, items to be disinfected need to be placed in a sealed space, and ozone is fed into the sealed space to achieve disinfection. The ozone feeding space is relatively sealed, and high concentration of ozone is required to achieve full disinfection. As a result, after the items are disinfected, part of the ozone remains in the sealed space. For example, the ozone remains inside a ventilator or in a ventilator tube. The ozone cannot be completely eliminated in a short period of time, and when a user takes out the items, a pungent smell will be diffused. On the other hand, a large amount of ozone inhalation will also harm human health. At present, none of devices and products for ozone disinfection of a ventilator on the market actively recycle ozone. The characteristic of active elimination is that a device may actively recycle all the remaining ozone generated, so that all these ozone may be filtered through an ozone filter and catalytically decomposed, thereby achieving a safe and reliable effect. Unlike a passive technology, the passive technology refers to placing a filter at a certain position in a disinfection space and simply adsorbing ozone through the surface without an external force. The effect of this technology is not good and the efficiency is low, and only the ozone around the filter can be simply adsorbed while the ozone remaining in other spaces such as hoses cannot be effectively adsorbed.

The above content is only used to help understand the technical solutions of this application, and does not mean that the above content is recognized as the prior art.

SUMMARY

A technical problem to be solved by the disclosure is to provide an ozone disinfection device, which may quickly disinfect a ventilator as well as a face mask and a hose, and after disinfection is completed, it may efficiently pump remaining ozone out and evacuate after filtration of the ozone, to achieve high-speed elimination of the remaining ozone while not generating ozone pollution to the surrounding environment.

Another technical problem to be solved by the disclosure is to provide an ozone disinfection system.

Yet another technical problem to be solved by the disclosure is to provide another ozone disinfection system.

Still another technical problem to be solved by the disclosure is to provide an ozone disinfection method.

In order to solve the above technical problems, the technical solution adopted by the disclosure is to provide an ozone disinfection device, which includes:

Embodiment I

The present embodiment provides an ozone disinfection device 100. The ozone disinfection device 100 is particularly suitable for disinfecting a ventilatory apparatus. The ventilatory apparatus includes a ventilator 600, a hose 602, and a face mask 603 that communicate in sequence. It can be understood that the ventilator 600 and the face mask 603 are connected by the hose 602, the ventilator 600 and the hose 602 are of a detachable connection structure, and the face mask 603 and the hose 602 are of a detachable connection structure.

In the present embodiment, referring to FIG. 1 , FIG. 3 , and FIG. 7 , the ozone disinfection device 100 includes: a sealed disinfection space 102 configured to receive a device to be disinfected or temporarily store ozone, the sealed disinfection space 102 communicating with a through hole 104, the through hole 104 allowing the insertion of a gas outlet end of the device to be disinfected; a gas distribution unit 200 including a first interface, a second interface, and a third interface that communicate with each other, the second interface being configured to communicate with a gas inlet end 601 of the device to be disinfected; an ozone generation unit 300 having an ozone outlet 301 communicating with the first interface, the ozone generation unit 300 including an ozone generator configured to generate ozone and a power apparatus configured to deliver the ozone to the first interface; a suction pump 400, the suction pump 400 having a suction port 401 and an exhaust port 402, the suction port 401 communicating with the third interface; a filter 500 having a plurality of exhaust holes 502 and at least one gas inlet 501, the gas inlet 501 of the filter 500 communicating with the exhaust port 402 of the suction pump 400; and a control module 700 configured to connect and control the operation of the ozone generation unit 300 and the suction pump 400.

In the present embodiment, the sealed disinfection space 102 is opened and closed in a drawer type. Specifically, referring to FIG. 1 , FIG. 3 , and FIG. 7 , the ozone disinfection device 100 includes an outer box and an inner box. The outer box includes a top cover, a base 101, and a peripheral side wall connected between the top cover and the base 101. A front side of the peripheral side wall is provided with a mounting hole into which the inner box can be inserted. The inner box has an opening on its upper end, and internally has the sealed disinfection space 102. The through hole 104 is provided on a front side of the inner box. When the inner box is inserted into the outer box from the mounting hole, the opening on the upper end of the inner box is sealed. At this time, the sealed disinfection space 102 can only communicate with the outside through the through hole 104. That is, if the through hole 104 is blocked, gas in the sealed disinfection space 102 will not escape.

In some other embodiments, the sealed disinfection space 102 may also be opened and closed in a flip type. A specific structure will not be described in detail in the disclosure. It should be understood that this is also the technical solution claimed by the disclosure.

In the present embodiment, referring to FIG. 3 , the ozone generation unit 300, the suction pump 400, and the filter 500 are all fixed to the base 101. The sealed disinfection space 102 is located on upper sides of the ozone generation unit 300, the suction pump 400, and the filter 500. Specifically, when the inner box is inserted into the outer box, the inner box is located just above the base 101, and the ozone generation unit 300, the suction pump 400, and the filter 500 are all located between the inner box and the base 101. By such design, an internal space of the outer box is fully utilized, making the entire ozone disinfection device 100 miniaturized and enhancing its portability.

In the present embodiment, referring to FIG. 3 , the ozone generation unit 300 communicates with the first interface of the gas distribution unit 200 through a first pipeline 201. The suction port 401 of the suction pump 400 communicates with the third interface of the gas distribution unit 200 through a third pipeline 203. The exhaust port 402 of the suction pump 400 communicates with the gas inlet 501 of the filter 500 through a fourth pipeline 204. The second interface of the gas distribution unit 200 communicates with the gas inlet end 601 of the device to be disinfected through a second pipeline 202. Preferably, the material of the first pipeline 201, the second pipeline 202, the third pipeline 203, and the fourth pipeline 204 is silica gel.

In some other embodiments, the material of the first pipeline 201, the second pipeline 202, the third pipeline 203, and the fourth pipeline 204 may also be Ethylene Propylene Diene Monomer.

In the present embodiment, the gas distribution unit 200 is a three-way pipe.

In the present embodiment, the filter 500 has the plurality of exhaust holes 502. Specifically, referring to FIG. 4 , the filter 500 includes a hollow housing, the housing has the plurality of exhaust holes 502 and the gas inlet 501, the gas inlet 501 is provided on lower sides of the plurality of exhaust holes 502, at least one filter layer 504 is disposed between the gas inlet 501 and the exhaust holes 502, and the housing internally has a buffer cavity 503 that is located on a lower side of the lowermost filter layer 504 and communicates with the gas inlet 501 of the filter 500. Since the filter 500 has a plurality of exhaust holes 502, non-polluting gas generated by the catalytic decomposition of ozone may be expelled more quickly, thus improving the ventilation efficiency of the filter 500. In addition, considering that solid particles such as fine dust may be included in fast-flowing ozone gas, the buffer cavity 503 is designed inside the housing, which functions to collect the solid particles included in the ozone gas for centralized removal. Preferably, two filter layers 504 are disposed between the gas inlet 501 and the exhaust holes 502, and there is a gap between the two filter layers 504. Therefore, the catalytic ozone decomposition ability and efficiency of the filter 500 may be improved to ensure that no ozone is included in the gas expelled from the filter 500. Here, at least one of the filter layers 504 is filled with manganese-containing particulate matters for catalytic ozone decomposition, so the ozone flowing through the filter 500 is decomposed into non-toxic and non-polluting oxygen under the action of the particulate matters to ensure the sanitation and safety of the surrounding environment.

In some other embodiments, three or more filter layers 504 may be disposed in the housing, and a certain gap is maintained between two adjacent filter layers 504. The ozone flowing through the filter 500 flows in from the gas inlet 501 of the filter 500, sequentially passes through the plurality of filter layers 504, and then is expelled from the exhaust holes 502. The ozone may be completely decomposed into non-toxic and non-polluting oxygen after being catalytically decomposed by the plurality of filter layers 504. It should be noted that substances filled in each filter layer 504 may be the same, and of course, may be different, as long as they have the function of absorbing or catalyzing the decomposition of ozone.

In the present embodiment, the power apparatus is a positive pressure gas pump, so that the ozone generated by the ozone generator is quickly expelled into the second interface, that is, the ozone generated by the ozone generator does not enter the second interface through a slow diffusion process, thus improving the work efficiency of the entire ozone disinfection device 100.

Referring to FIG. 1 and FIG. 2 , when disinfecting the ventilator 600 and the face mask 603 and the hose 602 thereof using the ozone disinfection device 100, the ventilator 600 communicates with the second interface through the second pipeline 202, after the sealed disinfection space 102 is opened, the hose 602 is inserted into the sealed disinfection space 102 from the through hole 104, the face mask 603 is put into the sealed disinfection space 102, the ventilator 600, the hose 602, and the face mask 603 are connected in sequence, and then the sealed disinfection space 102 is closed. After the above operations are completed, the control module 700 activates the ozone generation unit 300, and ozone generated by the ozone generation unit 300 flows into the ventilator 600, the hose 602, the face mask 603, and the sealed disinfection space 102 in sequence through the gas distribution unit 200, thereby performing ozone disinfection treatment on the ventilator 600, the hose 602, and the face mask 603. After the disinfection is completed, the control module 700 controls the ozone generation unit 300 to stop working and activates the suction pump 400, the suction pump 400 generates a strong negative pressure, and pumps all the ozone remaining inside the sealed disinfection space 102, the face mask 603, the hose 602, and the ventilator 600 to the filter 500, and the filter 500 performs catalytic decomposition treatment on the ozone flowing through, and then evacuates, thereby eliminating the ozone remaining inside the sealed disinfection space 102, the ventilator 600, the hose 602, and the face mask 603, and protecting a user from inhaling the remaining ozone when using the disinfected ventilator 600, hose 602 and face mask 603 while not causing ozone pollution to the surrounding environment. The safety and environmental protection of the ozone disinfection device 100 are improved. Compared with the existing passive ozone disinfection technology, the ozone disinfection device has the advantages of higher efficiency, high speed, safety, and environmental protection.

Referring to FIG. 5 and FIG. 6 , when disinfecting the face mask 603 and the hose 602 using the ozone disinfection device 100, the hose 602 communicates with the second interface through the second pipeline 202, after the sealed disinfection space 102 is opened, the hose 602 is inserted into the sealed disinfection space 102 from the through hole 104, the face mask 603 is put into the sealed disinfection space 102, the hose 602 and the face mask 603 are connected, and then the sealed disinfection space 102 is closed. After the above operations are completed, the control module 700 activates the ozone generation unit 300, and ozone generated by the ozone generation unit 300 flows into the hose 602, the face mask 603, and the sealed disinfection space 102 in sequence through the gas distribution unit 200, thereby performing ozone disinfection treatment on the hose 602 and the face mask 603. After the disinfection is completed, the control module 700 controls the ozone generation unit 300 to stop working and activates the suction pump 400, the suction pump 400 generates a strong negative pressure and pumps all the ozone remaining inside the sealed disinfection space 102, the face mask 603, and the hose 602 to the filter 500, and the filter 500 performs catalytic decomposition treatment on the ozone flowing through and then evacuates, thereby eliminating the ozone remaining inside the sealed disinfection space 102, the hose 602, and the face mask 603, and protecting a user from inhaling the remaining ozone when using the disinfected hose 602 and face mask 603 while not causing ozone pollution to the surrounding environment. The safety and environmental protection of the ozone disinfection device 100 are improved. Compared with existing passive ozone disinfection technologies, the ozone disinfection device has the advantages of higher efficiency, high speed, safety, and environmental protection.

After experimental tests, all the remaining ozone after disinfection may be quickly recycled and then safely treated through the ozone filter 500, realizing active elimination of the ozone remaining in the ventilator 600, the hose 602, and the sealed disinfection space 102. The characteristic of the disclosure is a technology of active ozone elimination. The characteristic of active ozone elimination is that the ozone disinfection device 100 may actively recycle all the remaining ozone generated, so that all these ozone may be filtered through the ozone filter 500 and catalytically decomposed into non-toxic and non-polluting gas, thereby achieving a safe and reliable effect. Unlike a passive technology in the prior art, the passive technology refers to placing the filter 500 at a certain position in a disinfection space and simply adsorbing ozone through the surface without an external force. The effect of the passive technology is not good and the efficiency is low, and only the ozone around the filter 500 can be simply adsorbed while the ozone remaining in other spaces such as the hose 602 cannot be effectively adsorbed.

In some other implementations, if the ozone generation unit 300 and the suction pump 400 are connected to the gas distribution unit 200 simultaneously, the situations where there is one or more interfaces of the gas distribution unit 200 for connection and delivery to the sealed disinfection space 102 fall within the scope of protection.

Further, the ozone disinfection device 100 is provided with an open button 103 and a handle 105. Referring to FIG. 7 , the open button 103 is disposed on the top cover of the outer box, and the handle 105 is disposed on the front side of the inner box.
